Andi Kleen 80a8c9fffa x86: fix oprofile + hibernation badness
Vegard Nossum reported oprofile + hibernation problems:

> mp_call_function_mask+0x194/0x1a0()

The usual problem: the suspend function when interrupts are
already disabled calls smp_call_function which is not allowed with
interrupt off. But at this point all the other CPUs should be already
down anyways, so it should be enough to just drop that.

This patch should fix that problem at least by fixing cpu hotplug&
suspend support.
